Here are some tips for searching in databases such as ProQuest. If you are getting thousands of results, it might be a good idea to narrow down your search, and if you are only getting a handful, you may need to broaden your scope a bit.
Be sure to keep a running list of good keywords you find in your research to mix and match as you go! Remember, research is an iterative process, meaning you won't know the best way to search a given topic until you try and fail a couple times.
Use ORs and parentheses to combine synonyms or multiple topics
(oil OR petroleum OR crude)
(antibiotic OR antiviral)
(woman OR girl OR female)
Truncate roots of important words* to find plurals and more
perform* (searches for perform, performance, performativity, etc.)
cell$
pregnan!
Insert a “wild card” [*?$!] to catch words with different spellings
wom?n
coloni#ation
odo$r
*Truncation and wild cards work differently in different databases. Check the help section of the database to learn what symbol to use and how to properly use it.
Combine concepts with AND to find more relevant sources
picasso AND Africa
internet AND privacy
bedrock AND Massachusetts AND hydrology
Use “double quotes” to find exact phrases
"rock art"
“African diaspora”
“invertible matrix”
Use proximity searching* to find words near each other
women NEAR violence
progressive NEAR/10 tax
"global warming" NEAR/20 "sea level"
 
 
*Proximity searching works differently in different databases. Check the help section of the database to learn how to properly use it.

Subject Headings are terms that are most commonly used to describe the topic that a resource covers. Unlike keywords, which are user generated, subject headings are created and maintained by an authoritative institution. For example, since Williams Libraries organizes our resources using the Library of Congress Classification, we also utilize Library of Congress Subject Headings to provide access to our collections by subject.
By clicking on any of the subject headings in this record, you will be brought to a new catalog search of resources also containing this subject heading.
